2. 2 physical natural matter :
 Matter is made up of particals.
 The particles of matter are very tiny.
 The particles of matter have space between them.
 The particles of matter are continusouly moving.
 The particles of matter attach each other.
Matter is made up of particle:
ACTIVITY- take some water in beaker and notes it’s level. Dissolve some salt or sugar in which the help
of glass rod. The salt dissolves in the water but the level of water does not change. This is because the
particles of water does not change. This shows that matter is made up of particles.

3. The particle of matter are very tiny:
 Dissolve two three crystal of potassium permangment in hundred ml of water in a
beaker.Take 10 ml of this solution and dissolve in 100 ml of water. Repeat this process
5-6 time.Ths show that few crystals of potassium permangment can a large volume
of water because of there are millions of particles in each crystal.
